What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Spinnaker Croft Mid-Size Skeleton

The Spinnaker Croft Mid-Size Skeleton is noted for its 40mm steel case, sapphire crystal, and 150m water resistance. One owner reports strong performance from the TMI NH70 movement at -3 seconds per day, with very nice lume. On balance, owners find the Spinnaker Croft Mid-Size Skeleton to be a pretty nice option, particularly for its movement performance and lume.

Seiko Prospex SPEEDTIMER SPEEDTIMER Mechanical Chronograph Limited Edition

The Seiko Prospex SPEEDTIMER SPEEDTIMER Mechanical Chronograph Limited Edition is praised for its well-executed heritage inspiration, clean dial, and balanced design, with its in-house caliber 8R48 noted as a solid movement. Owners appreciate the Zaratsu polishing and the column wheel and vertical clutch on the 8R48 movement, considering it good value. Some find the date wheel deep-set and the bracelet lacking micro-adjustments. The 42.5mm x 15.1mm case size may be large for some wrists. On balance, owners and reviewers rate the Seiko Prospex SPEEDTIMER SPEEDTIMER Mechanical Chronograph Limited Edition highly for its heritage design and solid in-house movement.
